Menopause is the point in life when menstrual periods stop permanently because the ovaries produce much less estrogen and progesterone. It is officially reached after 12 consecutive months without a period, and for most women it happens around the early fifties. It is a natural life stage, not an illness — but the hormonal changes around it can be felt for years, and they are worth understanding.

The three stages

Perimenopause is the transition, often beginning in the mid-forties. Hormone levels fluctuate, periods become irregular — closer together, further apart, heavier or lighter — and symptoms come and go. This stage can last several years. Menopause itself is the milestone: the 12-month mark after the final period. Everything after that is postmenopause, which lasts for the rest of life, with symptoms usually fading over time while the long-term effects of lower estrogen, such as bone thinning, become more relevant.

Common symptoms

Hot flashes and night sweats are the best-known symptoms — a sudden wave of heat, flushing, and sometimes a racing heartbeat, lasting from seconds to several minutes. Sleep often suffers, whether from night sweats or on its own. Many women notice mood changes, anxiety, or low mood; difficulty concentrating ("brain fog"); vaginal dryness and discomfort; changes in libido; and gradual changes in weight, hair, and skin. Not everyone gets every symptom, and severity varies enormously — some women pass through with barely a hot flash, while for others symptoms are disruptive for years.

Looking after long-term health

Lower estrogen affects more than periods. Bone loss speeds up after menopause, raising the risk of osteoporosis and fractures, and the protective effect estrogen had on the heart and blood vessels fades, so cardiovascular risk gradually rises toward men's levels. This is why the menopause years are a good time to review bone health, blood pressure, cholesterol, and screening schedules with a clinician — and why exercise, not smoking, and a calcium- and vitamin-D-aware diet matter.

What helps

Options range from lifestyle measures — dressing in layers, regular exercise, limiting alcohol and caffeine for sleep and flashes — to medical treatments, including hormone therapy for suitable candidates and several non-hormonal medicines for specific symptoms. Which options make sense depends on your symptoms, history, and preferences, and it is a genuinely individual decision to work through with your clinician.

Frequently Asked Questions

At what age does menopause usually happen?

The average is around 51, with a typical range from the mid-forties to the mid-fifties. Menopause before 40 is called premature menopause and should be evaluated by a clinician.

How long do hot flashes last?

They often continue for several years around the transition — for many women, somewhere in the range of 4 to 7 years in total, though this varies widely.

Can you get pregnant during perimenopause?

Yes. Ovulation becomes irregular but does not stop until menopause is complete, so contraception is still needed if pregnancy is not desired.

Is hormone therapy safe?

It depends on the individual — her age, time since menopause, and medical history. For many healthy women under 60 it is an effective option for symptoms; the balance of benefits and risks is personal and should be reviewed with a clinician.
